re PR c++/26696 (ICE with statement forming unused static member function reference)
PR c++/26696
* cvt.c (convert_to_void): Replace a subexpression with no side
effects with void_zero_node.
* tree.c (is_overloaded_fn): Look through COMPONENT_REF.
(get_first_fn): Ditto.
* decl.c (grokdeclarator): No need to look through COMPONENT_REF.
